nhooyr.io/websocket now resolves to github.com/nhooyr/websocket-old and its
README is a one-line deprecation pointing at coder/websocket. Its last three
releases (v1.8.15-17) all shipped on 2024-08-10 as the redirect; the fork has
shipped through 2026-06-15.
The version number decreases (v1.8.17 -> v1.8.15) because both paths tagged in
the same space, but the coder release is ~2 years newer. Import path only; the
9 API symbols used are unchanged.

Client now has three send channels:
- sendHigh (64 slots): DMs, mentions — drained first by writePump
- send (256 slots): chat messages, reactions — drained second
- sendLow (64 slots): typing, presence — drained last, dropped on overflow
writePump drains high-priority messages before checking normal/low.
PubSub gains PublishHigh/PublishLow alongside existing Publish.
EmitEvents routes events by priority:
- High: SequencedDMEvent, UserTargetedEvent
- Normal: ChannelEvent, VoiceChannelEvent
- Low: ExcludeSenderEvent (typing), PresenceEvent
Slow clients get typing/presence dropped first (sendLowMsg silently
drops), then disconnect on normal buffer overflow, ensuring DMs are
never lost to typing indicator backpressure.

- I-1: Add key holder election in Hub (lowest userID per channel); reject
non-key-holder voice_e2ee_offer with NOT_KEY_HOLDER error
- I-2: Accept raw (unpadded) base64 in E2EE announce/offer handlers via
decodeBase64Loose fallback
- I-6: Copy E2EE public key value while h.mu.RLock is held in getClientE2EEPubKey
- I-7: Lower loginRateLimitPerMinute from 60 to 5
- C-1: TOCTOU fix — target channel check held under same lock as client lookup
- C-2: Include is_key_holder bool in voice_token payload so client knows
whether to initiate key distribution
- M-5/M-6: Add ErrCodeBadPayload/ErrCodeNotKeyHolder error constants
- Fix pre-existing api build errors: block_handler.go getUserFromContext,
router.go RequirePermission arg count
- Add user_blocks table to all test DB schemas (ws, api DM)
- Add voice_e2ee_test.go and constants_test.go covering all fixes
Replace server-generated symmetric keys with client-side ECDH P-256 key
exchange. The server now only relays opaque public keys and encrypted
room key blobs — it never sees the actual room encryption key.
Protocol:
- voice_e2ee_announce: clients broadcast ECDH public keys
- voice_e2ee_offer: key holder wraps room key for each peer via ECDH+HKDF+AES-GCM
- Key rotation on participant leave (forward secrecy)
Server changes:
- Remove VoiceE2EEKeys (server-side key generation)
- Add relay handlers for announce/offer messages
- Store per-client ECDH public keys on Client struct
- Send existing public keys to new joiners during voice state sync
Client changes:
- New e2eeCrypto.ts: ECDH P-256, HKDF-SHA256, AES-256-GCM key wrapping
- LiveKitSession generates keypair on join, manages key holder election
- Key holder generates room key and wraps for each peer
- Non-holders wait for offer before connecting to LiveKit
- Room key rotated when any participant leaves

BUG-123: Register client BEFORE writing replay/ready data so broadcasts
during the write window queue in the send buffer instead of being lost.
On handshake failure, unregister before closing.
BUG-124: sendMsg/trySendMsg now close the send channel on buffer
overflow, forcing a disconnect → reconnect with replay recovery
instead of silently dropping messages and diverging state.
- Add syncutil package with deadlock-detecting mutex (build-tag switchable)
- Add main_test.go TestMain scaffolding across all server packages
- Harden concurrency in ws, admin, auth, and updater packages
- Update CI workflow, go.mod/sum, Cargo.lock, and root changelogen tooling
- Video grid: sync stream type attribute on updates, add screenshare data attribute
- Dispatcher: handle voice_token messages, improve video track event handling
- LiveKit session: add video track publication support
- Hub: stale client timeout cleanup, improved voice state management
- Voice join/leave: context propagation, better error handling
- Livekit webhook: structured event handling with room/participant data
- Server DB: voice query improvements, new test coverage
- WS integration tests: expanded coverage for voice and LiveKit flows
- Gitignore: add internal dev tools directory, owncord-server.exe

Camera fixes:
- Optimistic setLocalCamera(true) before async setCameraEnabled for instant
button highlight, with revert on failure
- Only call checkVideoMode when camera-relevant state changes, not on every
speaking poll tick (100ms)
- VideoGrid.addStream updates existing cells in place instead of
destroy+recreate to prevent black frame flashes
- VideoModeController tracks localTileAdded to avoid redundant addStream calls
Security & hardening (from prior session review):
- Settings store key allowlist prevents arbitrary key writes
- Certificate fingerprint validates SHA-256 colon-hex format
- CredentialData Debug impl redacts token and password
- LiveKit config file written with 0600 permissions
- Token TTL reduced from 24h to 4h
- Null-check on client.user before token generation
- Thread-safe getChannelID/trySendMsg helpers on Client
- Warn on default dev LiveKit credentials
- Devtools feature-gated behind cfg(feature = "devtools")
- Updater uses configure_client for self-signed cert acceptance
- Clamp voice sensitivity input to 0-100 range
- Clear lastConnectToken/Host on logout
- Fix animation frame leak in VoiceAudioTab mic meter
- Fix SDP signaling race condition: add per-client negoMu to serialize
renegotiateParticipant / handleVoiceOffer / handleVoiceAnswer so
concurrent OnTrack goroutines don't race through rollback
- Fix handleVoiceLeave triple-fire: early return when clearVoice()
returns zeros so ICE callbacks don't re-enter and corrupt state
- Fix SQLite SQLITE_BUSY errors: add busy_timeout=5000 pragma and
SetMaxOpenConns(1) for file-based databases
- Fix deafen bypass: new remote audio elements now respect localDeafened
state so late-arriving streams are muted immediately
- Add debug-level logging for SDP negotiation, track fan-out, ICE
candidates, voice state changes, room lifecycle, and participant
add/remove
- Bump version to 1.1.1
- CRIT-2: Prevent HTTP header injection in Content-Disposition via mime.FormatMediaType
- HIGH-1: Call hub.GracefulStop() on server shutdown to clean up WebSocket/voice state
- HIGH-2: Remove double send on serveErr channel that caused goroutine leak
- HIGH-3: Handle GetUserByID error after registration to prevent nil panic
- HIGH-4: Return nil,nil on sql.ErrNoRows in GetAttachmentByID (matching codebase convention)
- HIGH-5: Add voiceDone channel to bound RTP goroutine lifetime on voice teardown
- Fix handleVoiceICE to return VOICE_ERROR when no PC (consistent with other voice handlers)
- Update tests to match corrected behavior
Server:
- Add message search and pinned messages support
- Add admin hub integration and live connection stats
- Update admin test mocks for hub interface
Client:
- Add data-testid attributes to components for E2E testing
- Add window management capabilities (position, size, maximize)
- Add prod E2E test config and script
- Fix CSS imports (use vite bundling instead of HTML link tags)
- Add inline styles to InviteManager overlay for reliability
- Update CHATSERVER.md references from WPF to Tauri
Docs:
- Update quick-start guide
